Which of the following generally speed up a reaction? check all that apply. a. increasing the activation energy b. removing any catalysts c. adding more heat d. shaking the container holding the reaction

C and D

Explanation:

A. When you increase the activation energy, the reaction will be slowed down.

The energies that a certain number of molecules have to be equal to or greater than the activation energy so that a chemical reaction can occur. If we increase the activation energy, it is harder for the reaction to occur.

B. Catalysts play a role in lowering activation energy for a reaction to occur more easily. Hence, removing catalysts is not a way to speed up a reaction.

C. Adding more heat or D. Shaking the container holding the reaction are two options that can help the molecules contact one another more frequently, thereby facilitating the occurrence of reactions.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

b
